Your engine might already be a 10.3 engine if it was delivered to Canada originally. You'll get more power out of the 3.4 engine and be safer on the compression ratio. 964 cams are supposed to be a nice upgrade to that engine.

The Canadian cars had the same motor specs as the USA cars, at least the 3.2's did....

Cheers
